It's not a matter of waiting, even with block or better at Mesaba. It's about backing up onto the taxiways and listening to ground complain and have a meltdown. There is TONS of taxi space on the "odd" side in the alley, so if there is room, ramp control will give us clearance to move around whoever is waiting, so generally, it's not a big deal. The problem is even worse on the "even" side of B/C where taxiway K parallels the concourse.
